Definitions
- This invention relates to the general subject of seismic exploration and, in particular, to methods for identifying structural and stratigraphic features in three dimensions.
- geophysical staff compile and interpret the 3-D seismic information in the form of a 3-D cube (See FIG. 4) which effectively represents a display of subsurface features.
- information can be displayed in various forms.
- Horizontal time slice maps can be made at selected depths (See FIG. 5).
- an interpreter can slice through the field to investigate reservoir issues at different horizons.
- Vertical slices or sections can also be made in any direction using seismic or well data.
- Time maps can be converted to depth to provide a structural interpretation at a specific level.
- Three-dimensional (3-D) seismic is being used extensively worldwide to provide a more detailed structural and stratigraphic image of subsurface reservoirs.
- 3-D seismic has accelerated during the last five years based on a proven track record that continues to grow.
- the 3-D payout has been measured by increased reserve estimates, cost savings from more accurate positioning of delineation and development wells, improved reservoir characterization leading to better simulation models, and the ability to predict more accurately future opportunities and problems during the production history of a field.
- 3-D seismic has also been used as an exploration tool to reduce drilling risk in structurally complex areas and to predict reservoir quality in undrilled areas.
- seismic data has been traditionally acquired and processed for the purpose of imaging seismic reflections.
- Changes in stratigraphy are often difficult to detect on traditional seismic displays due to the limited amount of information that stratigraphic features present in a cross-section view. Although such views provide an opportunity to see a much larger portion of these features, it is difficult to identify fault surfaces within a 3-D volume where no fault reflections have been recorded.
- seismic data is not known to have been acquired or used for the purpose of imaging seismic discontinuities instead of seismic reflections.
- a method for the exploration of hydrocarbons.
- the method comprises the steps of: obtaining a set of seismic signal traces distributed over a pre-determined three-dimensional volume of the earth; dividing the three-dimensional volume into a plurality of vertically stacked and generally spaced apart horizontal slices; dividing each of the slices into a plurality of cells that are arranged into laterally extending rows and columns and that have portions of at least three generally vertically extending seismic traces located therein; measuring across each of the cells the cross-correlation between one pair of traces lying in one vertical plane to obtain an in-line value and measuring the cross-correlation between another pair of traces lying in another vertical plane to obtain a cross-line value that are estimates of the time dip in an in ⁇ line direction and in a cross-line direction; combining the in-line value and the cross-line value to obtain one coherency value for each of the cells; and displaying the coherency values of the cells across at least one horizontal slice.
- This technique is particularly well suited for interpreting fault planes within a 3-D seismic volume and for detecting subtle stratigraphic features in 3-D. This is because seismic traces cut by a fault line generally have a different seismic character than traces on either side of the fault. Measuring trace similarity, (i.e., coherence or 3-D continuity) along a time slice reveals lineaments of low coherence along these fault lines. Such coherency values can reveal critical subsurface details that are not readily apparent on traditional seismic sections. Also by calculating coherence along a series of time slices, these fault lineaments identify fault planes or surfaces.
- FIG. 1 illustrates an arrangement of geophones to obtain 3-D seismic data from the earth's subsurface for processing in accordance with the present invention
- FIG. 2 is a plan view of the arrangement shown in FIG. 1 ;
- FIG. 3 is a representation of the seismic traces laying in a plane passing through one row of geophones shown in FIG. 2;
- FIG. 4 is a pictorial representation of the information obtained from processing 3-D seismic data
- FIG. 5 is a pictorial representation of a horizontal time slice of 3-D seismic data processed in accordance with the prior art.
- FIG. 6 is a pictorial representation of a horizontal time slice of 3-D seismic data processed in accordance with the present invention.
- the first step is to obtain a set of seismic data in the form of seismic signal traces distributed over a three dimensional volume of the earth. Methods by which such data is obtained and reduced to digital form for processing as 3-D seismic data are well known to those skilled in the art.
- the next step is to generate a "discontinuity cube.” This is done by applying a coherency algorithm to the 3-D seismic data. This algorithm may take many forms. Whatever its form, its function is to compare the similarity of nearby regions of seismic data within the 3-D seismic volume. If a trace segment is similar to its neighbors (e.g., in the in-line and cross-line directions), it is assigned a low discontinuity value; if a trace segment is not similar to its neighbors, it is assigned a high discontinuity value.
- FIG. 2 is a plan view of a portion of 3-D seismic volume. In order to measure discontinuity, a trace segment at one point A is compared to adjacent trace segments B and C. One way to compute trace similarity is described below.
- autocorrelations used to normalize the cross-correlation, and where w+w is the length in msec of the correlation window. It is important to choose w large enough so the assumption of zero mean is valid. Values on the order of a seismic wavelet are appropriate. Other methods of normalization may be used (e.g., product of the energies of the traces, etc.).
- cross correlation is one method of combining two waveforms to measure the similarities of the waveforms.
- Autocorrelation is a method of combining a waveform with itself. See Sheriff's "Encyclopedic Dictionary of
- the direction of apparent time dip in the x and y directions is estimated to be that lag (i.e., tlagx and tlagy) that has the greatest (i.e., most positive) cross-correlation.
- lag i.e., tlagx and tlagy
- This value serves as a rather robust estimate of signal discontinuity within geologic formations as well as signal discontinuities across faults and erosional unconformities.
- subroutine COH calculates an output trace "rho" containing coherence coefficients using a running window cross-correlation algorithm where:
- lags specifies the number of lags (relative time shifts) to do each side of "0" in the cross-correlation
- subroutine CROSS calculates a series of normalized cross- correlation coefficients, returning the largest coefficients for each direction in "rhol " and "rho2". The time shift at which the maximum coefficients occur is returned in "tshfl” and “tshf2"; these times are not used.
- Subroutine COH is called repeatedly, once for every trace in the input seismic amplitude volume, to produce a new 3-D data volume or "coherency cube" containing coherence coefficients.
- nlags max(0, min(lags, maxlags))
- Landmark and GeoQuest interpretive workstations can be used to view and interpret faults and stratigraphic features by loading the discontinuity cube as a seismic volume.
- Visualization software e.g.,
- Landmarks's SeisCube software may be employed to rapidly slice through the discontinuity volume to aid in understanding complex fault relationships.
- Discontinuity displays can reduce interpretation cycle time when used in selecting which seismic lines to interpret, enabling the interpreter to work around faults and poo ' r data areas.
- subtle stratigraphic features and complex faulting which are not readily apparent on traditional seismic displays can be rapidly identified and interpreted.
- FIG's. 5 and 6 are side by side comparisons of the same seismic information displayed and processed conventionally and in accordance with the present invention. Fault lines are readily apparent in FIG. 6.
- Coherency maps have been run on several 3-D surveys. At depths of reasonable data quality, approximately 90% of the faults can be readily identified. Faults were identified on coherency maps which were very subtle on seismic sections, but clearly present on the coherency maps because of the robustness of the method and the map perspective of fault patterns. Since coherency maps can be run on uninterpreted time slices, the present invention offers a means to greatly accelerate mapping of the structural framework and to reveal details of fault relationships which would otherwise be interpreted only through tedious fault picking.
- 2-D seismic coherence maps were generated along picked horizons and clearly identified shale diapirs in offshore Nigeria. In offshore Gulf of Mexico, the technique readily identified diapiric structures.
- fault lines can predict flow patterns in a reservoir and communication between injector and producing wells, for example. Seismic discontinuities can also provide the needed link to enable reservoir prediction between the wells and establish reservoir continuity and flow patterns across a field.
- Coherency mapping of 3-D seismic is an extremely powerful and efficient tool for mapping both structure and stratigraphy.
- the new method is particularly sensitive to any lateral variation in wavelet character and therefore is particularly sensitive to the common causes of lateral variations in the wavelet (i.e., fault displacement or stratigraphic variations).
- This 3-D method analyzes a time-slice or horizon based interval and measures the maximum of the normalized cross-correlation in the in-line and cross-line directions.
- the discontinuity cube will clearly highlight fault planes as zones of high discontinuity. However, these zones may not be clearly in areas of lower signal-to-noise ratio.
- a method of enhancing these fault zones involves the application of a "median planar operator.” Faults in the earth's subsurface generally express themselves as planes or surfaces. In the case of a curved fault surface, a series of small flat planes may be used to approximate the fault surface. In accordance with this aspect of the invention, a small planar operator is used to enhance (i.e., a "filter") the identification of subtle stratigraphic features. First, a small region of seismic data is selected around a center value.
- This region may be formed from a plurality of the cells used to form the "coherency cube.”
- a small fault plane is then mathematically inserted into the region, and the median value of the points within the plane is calculated for the dip and azimuth that best aligns with the zone of high discontinuity. This median value is then assigned to the center value of a new array.
- the region of data is shifted (e.g., by one row) and the process is repeated until each point in the previously determined discontinuity cube has been analyzed as a center value.
- the end result is a completely new discontinuity cube with fault planes enhanced and noise and stratigraphic features (i.e., non-planar features) attenuated. These stratigraphic features may be separated by subtracting the new discontinuity cube from the old discontinuity cube without the planar filter application.
- stratigraphic features have been generally identified on time slices where dips were low; and consequently, the time window captured a narrow statigraphic section. In areas of higher dip, the method should work on picked horizons. Therefore, as a stratigraphic mapping tool, there is good reason to believe that new levels of detail can be mapped than previously, although this may require mapping of the horizon of interest.
